Rapid Expansion of Cell and Gene Therapy (CGT) Market

– CGT is a revolution of therapeutic innovations in the healthcare and life sciences industry

– Unlike conventional pharmacological (drug) therapies, which are often required throughout the duration of the disease, CGT is designed to be one-off

– Gene therapy involves the delivery of a vehicle to engineer the patient’s gene so as to treat or stop a disease

– Cell therapy involves the transplantation of human cells to replace or repair non-regenerative damaged tissues

How are cGMP and GMP different?

At the most basic level, GMP stands for Good Manufacturing Practice, standards set by regulatory agencies for ensuring the quality and safety of the manufactured drug products; the “c” of cGMP stands for current, designating the most advanced version of GMP with the latest technologies, regulations and rules.
